You know, the Twelfth Step is carrying the message. If you only go to meetings when you "need" one, who is there to help the newcomer? Part of the reason so many Al-Anon meetings turn into bitch-fests or sob-fests (as the ones I used to go to sometimes did) is because there isn't enough solid recovery in the room.
If you need a group that meets at a better time, start one. Start leading meetings so you know how to do it. Service is good for everyone--not just alcoholics in AA.
